Section 2 -- Classification Rules

2.1 Private Investor vs Professional Trader

• Distinction critical — The distinction between private investor (private Vermögensverwaltung) and professional trader (gewerbsmässiger Wertschriftenhandel) is the most critical classification in Swiss crypto taxation.

Private Investor vs Professional Trader

Classification	Capital Gains	Income Tax	Wealth Tax	Social Security
Private investor	TAX-FREE	Only on income events (staking, mining, etc.)	Yes — annual wealth tax	No (on trading gains)
Professional trader (selbständig Erwerbstätig)	TAXABLE as business income	Federal + cantonal income tax (up to ~40%)	Yes	Yes (~10% AHV/IV/EO on net earnings)

2.2 Kreisschreiben Nr. 36 — Safe-Haven Criteria

• Kreisschreiben Nr. 36 five cumulative criteria — The ESTV's Kreisschreiben Nr. 36 (27 July 2012, originally for securities, now applied to crypto) defines five cumulative criteria. If ALL five are met, the taxpayer is conclusively a private investor. (Kreisschreiben Nr. 36 (27 July 2012))

Safe-Haven Criteria (Kreisschreiben Nr. 36)

#	Criterion	Threshold for Private Investor
1	Holding period (Haltedauer)	Minimum 6 months
2	Transaction volume (Transaktionsvolumen)	Less than 5× the portfolio value at start of year
3	Capital gains as share of income (Kapitalgewinne als Einkommensanteil)	Realised capital gains < 50% of taxable income
4	Debt financing (Fremdfinanzierung)	No leverage/borrowed funds; or investment income > attributable debt interest
5	Derivatives (Derivate)	Derivatives used only to hedge existing positions

• Critical rules — All five criteria must be met cumulatively — failure on even one may trigger professional classification. If safe-haven criteria are NOT met, it does not automatically mean professional trader status — a holistic assessment follows. The holistic assessment emphasises transaction volume/frequency and use of leverage (Federal Supreme Court 2C.868/2008, 23 October 2009) (Federal Supreme Court 2C.868/2008, 23 October 2009)

2.3 Indicators of Professional Trading (Holistic Assessment)

If the safe-haven test fails, the following factors are weighted (in order of importance per Federal Supreme Court precedent):

Indicators of Professional Trading (ESTV Kreisschreiben Nr. 36; BGer 2C.868/2008; BGer 2C.766/2010; BGer 2C.385/2011)

Factor	Weight	Indicates Professional
Transaction volume and short holding periods	Primary	High volume, day-trading, swing-trading
Use of substantial borrowed funds	Primary	Lombard loans, margin trading, leveraged positions
Systematic, planned approach	Secondary	Dedicated software, algorithmic trading, full-time activity
Specialist knowledge from professional position	Secondary	Working in finance/crypto industry
Income dependency	Secondary	Trading profits fund living expenses
Continuous, recurring losses	Contra-indicator	Suggests hobby, not professional activity

2.4 Consequences of Professional Trader Classification

Consequences of Professional Trader Classification

Aspect	Treatment
All capital gains	Taxable as self-employment income
All capital losses	Deductible against other income
Transaction costs	Fully deductible as business expenses
AHV/IV/EO social contributions	~10% of net self-employment income
Income tax rate	Combined federal + cantonal: up to ~40% (varies by canton and income level)
Accounting obligations	Proper bookkeeping required

Section 3 -- Rate Tables

3.1 Wealth Tax (Vermögenssteuer)

• Wealth tax levied by cantons only — Wealth tax is levied by cantons and municipalities only — there is no federal wealth tax on private individuals.

Wealth Tax by Canton

Canton	Approximate Effective Rate (on net taxable wealth)	Notes
Zug	0.15%–0.30%	One of the lowest; crypto-friendly reputation
Nidwalden	0.15%–0.25%	Very low
Schwyz	0.20%–0.35%	Low
Zurich	0.30%–0.60%	Moderate
Bern	0.35%–0.65%	Moderate
Basel-Stadt	0.40%–0.75%	Higher
Geneva	0.50%–1.00%	Among the highest
Vaud	0.50%–0.80%	Higher

Rates are progressive — higher net wealth = higher marginal rate. Most cantons grant exemptions of CHF 50,000–100,000 for single taxpayers and CHF 100,000–200,000 for married couples. Smaller crypto portfolios often remain below the exemption threshold and pay no wealth tax. Wealth tax applies to the total net wealth (all assets minus liabilities), not just crypto

3.2 Income Tax Rates (If Professional Trader)

Income Tax Rates

Level	Maximum Marginal Rate
Federal (direkte Bundessteuer)	11.5%
Cantonal + municipal	~15%–35% (varies widely)
Combined maximum	~35%–42% (depending on canton)

3.3 Social Security (If Professional Trader)

Social Security

Contribution	Rate
AHV/IV/EO (self-employed)	~10% of net self-employment income (maximum; declining scale)
Additional social security	Varies by canton

3.4 ESTV Crypto Valuations — Kursliste 2025 (Selected)

The ESTV publishes official CHF valuations for the most common cryptocurrencies as of 31 December each year.

ESTV Crypto Valuations (ESTV Kursliste 2025; ictax.admin.ch)

Cryptocurrency	ESTV Value 31.12.2025 (CHF)
Bitcoin (BTC)	69,571.99
Ethereum (ETH)	2,364.08
Others	Published on ESTV Kursliste (ictax.admin.ch)

• If a token is not on the Kursliste — Use the documented market value from a reputable exchange (e.g. Coinbase, Kraken, Binance) as of 31 December 2025. Retain evidence. (ESTV Kursliste 2025; ictax.admin.ch)

Section 4 -- Cost Basis Methods

4.1 Private Investors — Limited Relevance

For private investors, cost basis tracking is not strictly required for tax purposes since capital gains are tax-free. However, it is strongly recommended to:

• Prove private investor status if challenged
• Document acquisition costs for tokens that generate income (staking/mining)
• Prepare for potential future tax law changes

4.2 Professional Traders — Full Tracking Required

Cost Basis Methods

Method	Status
FIFO (First In, First Out)	Accepted; commonly used
Average cost	Accepted
Specific identification	Accepted if documented
LIFO	Not standard practice

4.3 Cost Basis Components

• Cost basis components — For professional traders, the acquisition cost includes: - Purchase price in CHF at date of acquisition - Exchange fees and commissions - Network/gas fees - Any costs directly attributable to the acquisition

Section 5 -- DeFi, Staking, Mining, and Airdrop Treatment

5.1 Mining

Mining (StP 20 Nr. 2 (Canton TG); ESTV Arbeitspapier Kryptowährungen)

Scale	Classification	Tax Treatment
Small-scale / hobby	May be treated as occasional income	Taxable as "übrige Einkünfte" (other income); amount = FMV at receipt
Commercial / regular	Self-employment (selbständige Erwerbstätigkeit)	Full income tax + social security; deduct equipment, electricity, and operating costs

• Note - Thurgau mining — The Canton of Thurgau's Steuerpraxis explicitly states: "Mining of Bitcoin through provision of computing power and receipt of income in Bitcoin constitutes taxable income from self-employment in all cases." Other cantons are generally aligned. (StP 20 Nr. 2 (Canton TG); ESTV Arbeitspapier Kryptowährungen)

5.2 Staking

Staking

Aspect	Treatment
Classification	Income (Einkommen) at FMV when rewards are received
Tax rate	Ordinary income tax rates (federal + cantonal)
Tax point	When rewards are accessible to the taxpayer
Wealth tax	Staked tokens remain in the wealth tax base (declared at 31 Dec FMV)
Cost basis for future sale	FMV at receipt date (relevant only for professional traders)

5.3 DeFi Lending

DeFi Lending

Activity	Treatment
Interest/yield received	Taxable as income at FMV when received
Principal returned	Not an income event (return of capital)
Principal lost (protocol failure)	Potential deductible loss for professional traders; limited relief for private investors

ESTV has not published comprehensive DeFi lending guidance. Conservative approach: treat all yield as taxable income.

5.4 Liquidity Providing

Liquidity Providing

Activity	Treatment
Adding to LP	Uncertain — may or may not be a disposal for professional traders
Fees/rewards earned	Taxable as income at FMV
Impermanent loss	Not addressed by ESTV

LP positions in DeFi are an evolving area.

5.5 Airdrops

Airdrops

Type	Treatment
Gratuitous airdrop (no action required)	Add to wealth tax portfolio at FMV; acquisition cost = CHF 0
Airdrop for services	Taxable as income at FMV when received

5.6 Hard Forks

Hard Forks

Aspect	Treatment
Original coin	Cost basis unchanged; continue to declare for wealth tax
New forked coin	Acquisition cost = CHF 0; add to wealth tax portfolio at FMV on 31 Dec
Private investor sale	Tax-free capital gain
Professional trader sale	Fully taxable

5.7 ICO/Token Participation

ICO/Token Participation (ESTV Arbeitspapier "Kryptowährungen und Initial Coin/Token Offerings (ICOs/ITOs)")

Aspect	Treatment
Investment in ICO/ITO	Acquisition cost = amount invested in CHF
Token received	Declare for wealth tax at FMV (or cost if no market price available)
Subsequent sale (private)	Tax-free capital gain
Subsequent sale (professional)	Taxable income

Section 6 -- NFT Treatment

6.1 General Classification

NFTs are treated similarly to other crypto-assets under Swiss tax law:

NFT General Classification

Aspect	Private Investor	Professional Trader
Purchase	Acquisition cost recorded	Business expense
Holding	Wealth tax at 31 Dec FMV (may be difficult to value)	Wealth tax + balance sheet item
Sale gain	Tax-free	Taxable as business income
Sale loss	Not deductible	Deductible business loss
Creation and sale	If occasional, tax-free; if regular, self-employment income	Business income

6.2 Valuation Challenges

• NFT valuation challenges — NFTs are generally NOT on the ESTV Kursliste. Valuation for wealth tax: - Use last sale price on a recognised marketplace (OpenSea, etc.) - If no recent sale, use acquisition cost or a reasonable estimate - If the NFT has no market value, declare at CHF 0 with a note

6.3 NFT Royalties

• NFT royalties — Secondary sale royalties received by NFT creators are treated as income (self-employment if regular, other income if occasional).

Section 7 -- Reporting Requirements

7.1 Tax Return Filing

Tax Return Filing

Element	Where to Report
Crypto holdings (wealth tax)	Wertschriftenverzeichnis (securities schedule) / État des titres — list each crypto with quantity and CHF value at 31 Dec
Staking/mining income	Einkommen / Revenu — declare as other income
Professional trading income	Einkommen aus selbständiger Erwerbstätigkeit — with profit & loss statement
Capital gains (private)	No reporting required (tax-free)

7.2 Wertschriftenverzeichnis — How to Declare Crypto

For each cryptocurrency held on 31 December:

Wertschriftenverzeichnis Fields

Field	What to Enter
Description	Name of cryptocurrency (e.g. "Bitcoin (BTC)")
Quantity	Number of units held
Valuation	ESTV Kursliste value per unit in CHF; or documented market value
Total value	Quantity × per-unit value
Location/custodian	Exchange name or "private wallet"

7.3 Filing Deadlines (Vary by Canton)

Filing Deadlines

Canton	Standard Deadline	Extension Available
Zurich	31 March	Yes (up to 30 September)
Bern	15 March	Yes
Zug	30 April	Yes
Geneva	31 March	Yes
Others	Typically 31 March	Varies

7.4 ESTV Kursliste Access

• Available at: ictax.admin.ch
• Published annually after year-end
• Covers major cryptocurrencies (BTC, ETH, and many others)
• Updated annually; check for the relevant tax year

7.5 Record-Keeping

Record-Keeping

Requirement	Detail
Retention period	10 years (Obligationenrecht Art. 958f) for professional traders; recommended 10 years for private investors
Records to maintain	Transaction logs, wallet addresses, exchange statements, ESTV Kursliste screenshots, staking/mining logs
Format	Electronic acceptable; exchanges' CSV exports plus on-chain evidence

7.6 CARF (Crypto-Asset Reporting Framework)

• CARF implementation — Switzerland has committed to implementing CARF by 2027. This will require Swiss crypto service providers to report user transaction data to the ESTV for automatic exchange with other jurisdictions.

Section 8 -- Loss Offset and Carry-Forward

8.1 Private Investors

Private Investors Losses

Scenario	Treatment
Capital loss on crypto sale	NOT deductible — capital gains are tax-free, so capital losses are tax-irrelevant
Wealth tax on depreciating assets	Wealth tax still applies on 31 Dec FMV (but lower value = lower wealth tax)

8.2 Professional Traders

Professional Traders Losses (DBG Art. 211)

Scenario	Treatment
Trading losses	Deductible against all other income (employment, self-employment, etc.)
Net operating loss	Can be carried forward for 7 years (DBG Art. 211; cantonal laws vary)
Transaction costs	Fully deductible
Social security impact	Losses reduce the base for AHV/IV/EO contributions

8.3 Stolen/Lost Crypto

Stolen/Lost Crypto

Scenario	Private Investor	Professional Trader
Hacked exchange	Remove from wealth tax (no longer held on 31 Dec)	Deductible loss
Lost private keys	May argue removal from wealth tax if permanently inaccessible	Deductible if documented
Exchange bankruptcy	Remove from wealth tax once definitively lost	Deductible loss

Section 9 -- Anti-Avoidance Rules

9.1 Professional Trader Reclassification

• Reclassification risk — The primary anti-avoidance mechanism is the ESTV's power to reclassify a private investor as a professional trader, thereby subjecting all gains to income tax. This is the most significant risk for active Swiss crypto investors.

9.2 Economic Substance

• Substance over form — Swiss tax authorities apply substance-over-form principles. Structures lacking economic substance (e.g. crypto held through shell companies in low-tax cantons purely for wealth tax reduction) may be challenged.

9.3 Cantonal Tax Competition

• Cantonal competition — While cantonal tax competition is legal and encouraged in Switzerland, moving cantonal domicile purely for wealth tax reduction is legitimate. However, the move must be genuine — a sham relocation may be challenged.

9.4 Intercantonal Double Taxation

• Intercantonal allocation — If a taxpayer has tax obligations in multiple cantons (e.g. property in one, domicile in another), allocation rules apply. Crypto is generally allocated to the canton of domicile.

9.5 International Exchange of Information

• International exchange participation — Switzerland participates in: - AEOI (Automatic Exchange of Information) — operational since 2018 - CARF (Crypto-Asset Reporting Framework) — by 2027 - Bilateral tax treaties with 100+ countries

Section 10 -- Worked Examples

Example 1 -- Private Investor, Tax-Free Gains + Wealth Tax

Input: Swiss resident in Canton of Zurich. Holds 5 BTC purchased in 2022 at CHF 25,000 each. Sold 2 BTC in June 2025 at CHF 65,000 each. Still holds 3 BTC on 31 December 2025. No leverage, no derivatives, holds > 6 months, no other trading. Total other taxable income: CHF 120,000.

Safe-haven test (Kreisschreiben Nr. 36):

1. Holding period ≥ 6 months:          YES (held since 2022)
2. Transaction volume < 5× start value: YES (2 sales vs portfolio of 5 BTC)
3. Capital gains < 50% of income:       CHF 80,000 gain vs CHF 120,000 income
                                         → 80,000 / (120,000 + 80,000) = 40% → YES
4. No leverage/borrowed funds:           YES
5. Derivatives for hedging only:         No derivatives used → YES

All 5 criteria met → PRIVATE INVESTOR

Tax computation:

Capital gains: 2 × (CHF 65,000 - CHF 25,000) = CHF 80,000
Capital gains tax: CHF 0 (tax-free for private investors)

Wealth tax:
  3 BTC held on 31.12.2025
  ESTV Kursliste value: CHF 69,571.99 per BTC
  Crypto wealth: 3 × CHF 69,571.99 = CHF 208,715.97
  (Added to other wealth for total net wealth calculation)
  Zurich wealth tax on CHF 208,716 portion: ~CHF 600–1,200 (depends on total net wealth and municipality)

Example 2 -- Professional Trader Classification

Input: Swiss resident in Canton of Zug. Made 500+ trades in 2025. Average holding period 2 weeks. Uses margin trading. Crypto gains = CHF 200,000. Other income: CHF 50,000 (part-time employment).

Safe-haven test:

1. Holding period ≥ 6 months:          NO (average 2 weeks)
2. Transaction volume < 5× start:      Likely NO (500+ trades)
3. Capital gains < 50% of income:       200,000 / 250,000 = 80% → NO
4. No leverage:                         NO (margin trading)
5. Derivatives for hedging only:         N/A

Multiple criteria FAILED → Safe haven NOT available

Holistic assessment strongly indicates professional trader:

- High volume (500+ trades): YES
- Short holding periods: YES
- Substantial leverage: YES
→ Classification: Professional trader (gewerbsmässiger Händler)

Tax computation:
  Taxable self-employment income: CHF 200,000
  Federal income tax: ~CHF 20,000 (11.5% marginal)
  Cantonal/municipal tax (Zug): ~CHF 16,000 (low-tax canton)
  AHV/IV/EO: ~CHF 20,000 (10%)
  Total tax burden: ~CHF 56,000 (~28%)

  Note: Can deduct all trading fees, exchange costs, and losses.
  Wealth tax also applies on remaining holdings at 31 Dec.

Example 3 -- Staking Income + Wealth Tax Only

Input: Swiss resident in Canton of Geneva. Holds 100 ETH, staked via Lido. Received 5 ETH in staking rewards during 2025 (FMV at receipt dates totalling CHF 12,500). No sales. Private investor (safe-haven met).

Tax computation:

Capital gains: None (no sales)
Capital gains tax: CHF 0

Staking income:
  5 ETH received, total FMV: CHF 12,500
  Taxable as ordinary income
  Combined federal + cantonal tax (Geneva, ~35%): ~CHF 4,375

Wealth tax:
  105 ETH held on 31.12.2025
  ESTV value: CHF 2,364.08 per ETH
  Crypto wealth: 105 × CHF 2,364.08 = CHF 248,228.40
  Geneva wealth tax (higher bracket canton): ~CHF 1,500–2,500

Total tax: ~CHF 5,875–6,875

Self-Checks

Before finalising any Switzerland crypto computation, verify:

• Kreisschreiben Nr. 36 safe-haven analysis completed (all 5 criteria)
• If safe-haven fails, holistic assessment documented
• ESTV Kursliste values used for 31 Dec wealth tax (check ictax.admin.ch)
• Tokens not on Kursliste valued from documented exchange rates
• Canton of residence identified (critical for wealth tax rates)
• Mining/staking income declared as ordinary income at FMV
• Wealth tax calculated on total crypto holdings at 31 Dec
• All values in CHF at applicable exchange rates
• Wertschriftenverzeichnis (securities schedule) completed with all crypto positions
• Professional trader consequences assessed (income tax + social security)
• Record retention of 10 years for professional; recommended same for private
• CARF reporting awareness (2027 implementation)

PROHIBITIONS

• NEVER assume all Swiss crypto is completely tax-free — wealth tax applies and income events (staking, mining) are taxable
• NEVER ignore the Kreisschreiben Nr. 36 safe-haven test — failure triggers professional trader risk
• NEVER use outdated ESTV Kursliste values — verify for the correct tax year
• NEVER ignore cantonal differences — wealth tax rates vary by 5–7× between cantons
• NEVER classify staking/mining income as tax-free capital gains — these are income events
• NEVER forget AHV/IV/EO social security contributions for professional traders (~10%)
• NEVER assume professional trader status is always disadvantageous — losses and costs become deductible
• NEVER omit crypto from the Wertschriftenverzeichnis — all holdings must be declared for wealth tax
• NEVER treat wallet-to-wallet transfers as disposals
• NEVER compute professional trader gains without tracking cost basis
• NEVER present crypto tax positions as definitive — always label as estimated and flag for professional review
